30 amp fuse for the power steering and one
25 amp fuse the ignition, PTO, etc. These are
standard plug-in type automotive fuses. Always
use the same capacity fuse for replacement.

pedals in the neutral position and the
PTO disengaged, release the parking
brake and try to start the engine. The
engine should not start.
• If it does, the parking brake switch must
be repositioned or replaced. See your
authorized service dealer. If the engine
does not start, engage the parking brake
and start the engine.
Seat Switch
With the drive pedals in the neutral position,
the parking brake engaged and the PTO

With the drive pedals in the neutral position,
the parking brake engaged and the PTO
disengaged, sit in the operator's seat and start
the engine. Engage the PTO and the blades
should start to rotate. Raise up slightly off the
operator's seat and the blades should stop. If
the blades do not stop when you dismount from
the operator's seat, the seat switch must be
replaced. See your authorized service dealer.
Electric PTO Clutch
This clutch operates when the engine is running,
the operator is in the operator's seat and the
PTO is engaged. This electric clutch is a normally
trouble free device. If a problem develops and
the blades do not turn, first check the 25 amp
fuse, then investigate the wiring harness and the
connections to the seat switch, the PTO switch
and the electric blade clutch. Then check the seat
switch, the PTO switch and finally the electric
blade clutch. If the PTO clutch is still not working
properly, see an authorized service dealer.
